1. Write the equation of a line through the points (-4,7) and (-6,2). 2. Write the equation of a line through the points (2,-9) and (2,6) 3. Write the equation of the line perpendicular to the line in #1 with the same x-intercept

Step-by-step explanation:

1. Write the equation of a line through the points (-4,7) and (-6,2). 2. Write the equation of a line through the points (2,-9) and (2,6) 3. Write the equation of the line perpendicular to the line in #1 with the same x-intercept

{ (-2,4) , (-1,2) , (0,0) , (1,-2) } data set indicates a strong negative correlation.

Step-by-step explanation:

Given Set of points are the following;

Set 1 - { (-3,8) , (-2,-6) , (-1,4) , (0,-2) }   , Set 2 - { (-2,-4) , (0,-2) , (2,0) , (4,2) }  and Set 3 - { (-2,4) , (-1,2) , (0,0) , (1,-2) }

Strong Negative Correlation occurs when value of one variable increase then value of second variable decreases.

Strong Positive Correlation occurs when value of one variable increase then value of second variable Also increases.

This can be check by marking them on graph paper.

Graph paper is attached.

From graph paper and definition Data Set 3  indicates a strong negative correlation.

Therefore,  { (-2,4) , (-1,2) , (0,0) , (1,-2) } data set indicates a strong negative correlation.
